Potion of combustion

I would really think a potion of combustion Would be cool. you drink it and you set on fire or maybe place fire wherever you walk or both, splash potion acts like a ghasts fireball and creates a small explosion and places some fire, lingering potion could create a zone where people can catch on fire themselves without setting the ground on fire, and the tipped arrows could be as powerful as a blaze’s fire charge and only place a block of fire to burn down forests from a distance or trigger tnt without needing the flame enchant and maybe the arrow could be more explosive the stronger the combustion level is (like combustion II). The potion of combustion could be brewed using a fireball to give it another much needed use.
